Liquid nitrogen flow controller.

Sierra s smarttrak line of digital high pressure mass flow meters and controllers with a high pressure option specializes in accurate mass flow measurement chromatography inlet fuel measurements and or control of nitrogen n2 gas one of the most commonly measured gases. Liquid nitrogen has a boiling point of 320 f 196 c. 0 bar 10 bar nominal diameter. It is a closely held company owned and operated by erik and lars rosaen.

The temperature difference between the product and the surrounding environment even in winter is substantial. 452 f 269 c 4k. Flow meter calibration hoffer flow controls inc. The biggest problem is that most meters on the market literally freeze up and stop working when metering these.

All valves are normally closed unless actuated. Cryocomp cryogenic valves are available from to 2 0 diameters in manual and actuated remote on off and flow control configurations. 107 kitty hawk lane elizabeth city nc 27909 ph. Cryocomp cryogenic valves are offered in globe right angle and y pattern configurations which allow for installation of up to 30 degrees out of vertical orientation.

Our valves are available from od to 12 nps diameters in manual remote actuated on off proportional flow control and check valve configurations. 252 331 1997 1 800 628 4584 fax. The function of the temperature controller is to pass liquid nitrogen through the system maintaining it at low temperatures. Built to withstand the extreme cold of liquid nitrogen and liquid oxygen these valves are cleaned and bagged for high purity applications.

252 331 2886 email. For air for nitrogen for liquids. Their fluid properties change wildly with small variances in temperature or pressure. Was incorporated in 1963.

Can be used as a stand alone flow. This family owned business started out making variable flow switches for the automotive industry and today services concrete defense chemical processing mining wastewater energy electronics laboratories medical and many other industries. The actuator is directly mounted to the valve body to minimize movement and reduce wear. Liquid nitrogen is a cryogenic liquid.

The result is precise flow control for many gas and liquid service applications. Working temp down to. Universal flow monitors inc. Liquid nitrogen carbon dioxide argon oxygen and lng lpg are some examples of cryogenic fluids which are perfect for a coriolis mass flow meter.

Cryogenic liquids are liquefied gases that have a normal boiling point below 130 f 90 c. They operate on electricity to automatically start and stop flow. High accuracy measurement for nitrogen gas in industrial research applications. To maintain this constant temperature a constant flow of liquid nitrogen is required.
